Skuntank

Choose 1 of your opponent's Pokémon that doesn't have any damage counters on it. This attack does 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)

Flip a coin. If heads, the Defending Pokémon is now Poisoned. Put 2 damage counters instead of 1 on the Defending Pokémon between turns.
